Q: Why do my car shut off when I stop

asked by on June 18, 2017

Why do my car cut off when I stop or cut on the AC

My car has 130358 miles.
My car's transmission is unknown to me.

The first and easiest thing to do is to check for air leaks. Any air that gets into the engine without going through the air mass meter will lean out the fuel mixture and affect the idle. Inspect the rubber hoses and boots to be sure they are in good condition and properly connected. Other problems that affect the idle could be a dirty throttle body or idle control valve. You can have these things checked at your convenience by contacting Your Mechanic. They can send a technician to your home or office to check out your problem idle and let you know what steps to take.
